By the fall of 1927 the Pentecostal revival from Bourgas extended to several outreaches. Appropriate recognition was given by the General Council of the Assemblies of God in their September, 1927 meeting. The Latter Rain Evangel also reported revival in Bulgaria, workers trained at the Bible School and a good number saved and baptized with the Holy Spirit.

With this avid success and the arrival of Nikolov’s first-born son on November 9, 1927 came the second attempt to unite Bulgarian Pentecostals. A preliminary meeting was held in February of 1928 in Rouse where the Union’s establishing meeting was scheduled for March 28 in Bourgas.

To no surprise, only 14 delegates representing five congregations attended. The delegates voted and received the Union’s by-laws and statement of faith, based on the same documents by the Assemblies of God in America. The first annual conference of the new Union followed in October in Varna. A national General Council was set and the Executive Committee was chaired by Pastor Nikolov – at the time of his appointment he was only 28 years of age.

Trained in the United States and familiar with the Assemblies of God structure, Nikolov purposed to replicate the same organization in Bulgaria. Unfortunately, most Bulgarian Pentecostals in 1928 did not have a clear perception of the Assemblies of God and hardly felt part of the denomination. With only 20 members, the new organization was a small minority and did not represent the vast diversity within Bulgarian Pentecostalism at the time. Neither did it cause the split among Bulgarian Pentecostals as often held. The official registration of the Pentecostal Union simply confirmed the deepening division among Pentecostals in Bulgaria that had taken place since Zaplishny was deported in 1924.
